SPECIFICATION formingpart of Letters Patent No. 781,497, dated January 31, 1905.

Appiiation flied nach 17, 1904. Seriana-198,639.

To all whom, it may concern:

Be it known that I, WILLIAM C. CULLITON,v a citizen of the United States, residingat Buffalo, in the county of Erie and State ofNew York, have invented certain new and .useful Improvements in Dumping Apparatus for Unloading Railway-Cars, of which the following vis a specification.

The apparatusis designed to receive a transporting-car having one side removed-such; for instance, as are usually used at stone'- crushing plants. ."When in vuse as a st onetransporting car and it is desired to dump the stone into the Crusher, one side of the platform` is raised to bring the same at an angle, and as the car is supported on and securely lheld to the platform it assumes the same angle as the platformand is held at such an angle untilits entire contents has been dumped into the lstone-crusher.

The object of the invention is to provide a tilting platform of simple construction which can be operated to dump a railway-car resting thereon by means of a pullrod and which will be returned to its-normal position automatically as soon as the contents of theV car has lbeen dumped and securely held vin such position. I

Other objects of the invention lie in the details of construction, which will be hereinafter described. Figure 1 represents a side elevation of the improved dumping apparatusv in its normal position. tioned on the platform ready to be dumped. Fig. 2 isv asimilar viewshowing the platform in its inclinedl or dumping position, the car being shown on the platform. Fig. 3 is a top -planViewshowing the platform-in its" normal position Without the car. Fig. 4 is a Verticalsectiontaken on line 4L 4, Fig. l, the platform being shown in its normal position.

. Fig. 5 is a similar view with the platform shown in its inclined or dumping position.

from which the car-is dumped.

timber is provided with journals or trunnions In this. View a carl is shown posi-Y Fig. is an enlarged fragmentary longitudinalsection of the longitudinal pivot-timber,

taken through one of the metal-faced trun- Anions.

from the pyOtal point of the platform, as at L C, in order toform a stop or support for the saidl platform when Vthe same is in its inclined or dumping position. otally connected with the foundation B by means of a longitudinal pivot-timber D, arrangedi underneath the platform at a point somewhat nearer to the side opposite to that This pivot- D, which are located near opposite endsl of the platform and revolve in bearings E, secured to two cross-beams.y The trunnions are formed by reducing the pivot-timber at two points and inclosing the said reduced portions inmetal casings F, each having a cylindrical outer face and being formed in two half-sections e e, Abolted together by meansof bolts "e, as clearly shown in Figs. (Saud-7. .w

The platform is usuallyformed of a .series of ties G, to which the rails H and I, formany Well-known manner. The raillI, Which islocated on that side of the platform adapted to be elevated when dumping the latter, is made somewhat longer than the rail H, so

'that a considerable portion of the weight of the car moved onto the platform will be sup-v ported by the foundation B. This arrangement also prevents depression of the platform when the car rides uponuthe same,` the ends of the portion of the rail I on the platform -being supported on the foundation .B, thus having the same solid support given the adjacent portions of said rail. The rail- H is,

by preference, provided with a raised outer portion forming a ledge L, which prevents displacement of the car when the platform is inclined by reason of the outer faces of the The platform is pivf ing a portion ofl the track A', are secured in j IOO wheels on the dumping side resting against the said ledge. A metal plate J is arranged parallel with the rail I, secured to the platform, and-projects upwardly therefrom. This plate is provided upon its upper edge with an outwardly-extending iiangej, and to the under side of the car, opposite to the dumping side, is also attached a plate K, provided with a groove le. The iange of the plate J is adapted to engage the groove in the plate K when the car is on the platform, thereby, with the aid of the ledge 7L on the rail H, securely holding the ear on the platform when the same is in its inclined or d um ping position.

To one of the beams of the foundation B are pivotally attached two dogs L L, which are confined in guide-straps N N, also attached to one of the foundation-beams. The upper ends of the dogs engage two of the cross-ties G G of the platform, thereby securely fastening the platform against movement on the foundation. The dogs are released from contact with the platform by means of a bar O, which is pivotally attached to the said dogsL L and is provided with an eye 0 at each end thereof, the eye at one end being engaged by one end of a pull-rod S and the eye at the other end having one end of a retractile spring Q, attached thereto, the other end of the said spring being' secured to one of the vertical beams of the foundation, as at R, the said spring serving to control the Operation of the bar O.

The center cross-tie T of the dumping-platform is provided at the elevating side of the latter with an eye t, and to this eye is attached one end of a rope U, that passes down over a pulley V and is wound around a drum V', the outer end of the rope being attached to a weight W. The pulley V and drum V are journaled in a frame X, arranged at the side of the platform opposite the dumping side, as shown in Figs. 1l: and 5.

To operate the dumping-platform, a loaded car is run upon the same, during which action the plateJ engages the plate K. The pull-rod S is then drawn in the direction of the dart e, Fig. l, causing the bar O to release thedogs L L from engagement with the platform and permitting the same to tilt or incline in order to discharge the contents of the car by reason ofthe platform being pivoted out of the medial line and also by reason of the weight of the car overcoming the weight W. After the car has been emptied it and the platform are automatically returned to their normal position by means of the weight W, this weight being sufficiently heavy to overcome the weight of the empty car and platform, at which times the dogs L L automatically engage the platform and fasten the same in position.

In Figs. 1I, 5, and 8 I have shown a friction band-brake consisting of a friction-disk Y, secured to the rope-drum V, a frictionbelt Z passing around the friction-disk and in contact therewith, the ends of the belt heilig fastened to pins e 21', projecting from the face of a bell-crank lever Z', that is secured to a crank-shaft Z2, loosely journaled in the frame beneath the rope-drum. This brake is intended to be brought into action in case the platform is returned too rapidly to its normal position, which is likely to occur in many instances where the platform has received a lightbuilt car designed to receive a lighter grade of stone or other material.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a car-dumping apparatus, the combination of a foundation, and a dun'n'iing-platform pivotally secured to said foundation and having a pivot-timber arranged lengthwise underneath the same, said pivot-timber being provided with reduced portions and having separable metal casings surrounding said reduced portions.
